This sentence was told by “Omar” about commander of faithful [AS], in various events and repeatedly. At first, we’ll quote its documents in Shiite books then we’ll quote what has written in Sunni books in this regard to be reliable for Sunni.

“Omar” ordered an insane woman and a woman who gave birth to a kid six month after marriage to be stoned, Ali [AS] said to him: indeed god almighty says: his bearing and weaning are thirty months and told him: god has lifted the incumbency form insane [is not obligated] …. Then “Omar” said: if it weren’t for Ali [AS] “Omar” would perish.

Someone came to “Omar” and said in response of a question about the way he passed the night, he said: I passed the night while I liked the temptation and I was reluctant accepting to truth and would confirm the Jews and Nazarenes and had faith to what I didn’t see and admitted to what hasn’t created, “Omar” sent someone to Ali [AS] when he they told him what that person said, Ali [AS] said: he’s right because, indeed, your children and properties are a temptation, and he is reluctant to truth, he means: death, because god says: death is truth, and he affirms the Jews and Nazarenes , god says:The Jews say the Nazarenes are not on anything, and the Nazarenes say it is the Jews who are not on anything, and he believes what he hasn’t seen, he means: god, and admits to what hasn’t been created, he means: day of resurrection, then “Omar” said: if Ali [AS] weren’t “Omar” would perish.

“Qazi Izzu Al din eji” a Sunni famous scholar in “Kalam” science quotes and confirms this narrative in the book “Mavaqef” to express the reasons of Ali’s [AS] superior amongst prophet’s [PBUH] companions.
